Slow Internet At Random Times (usually During Peak Hours)?
Apr 30, 2011
isp is Comcast. They have had 2 techs come out here to look at problem and found nothing. I'm on a wireless connection with router in the next room. Modem was replaced a week ago and still problem persists. Landlady says she has no problem (shes the one in the next room and is connected directly) but I think that because she doesn't notice (I play online games so its very noticeable). I have excellent signal from router. This is my report:

Network running about 60 computers, most of which are running windows 7 professional. Some are on a domain, some are not.At (seemingly) random times, some computer on the network will lose the ability to browse websites (including the web interfaces of networked devices). I can't identify what circumstances cause this to occur. I only find out about it when someone calls me.From the affected computer:I can ping sites I can ping our Cyberoam UTM (which acts as our DNS, DHCP, and firewall)disabling/enabling connection doesn't fix the problem releasing/renewing ip doesn't fix the problem flushing dns doesnt fix the problem uninstalled antivirus on two test machines, problem still randomly manifests.replaced the Cyberoam with newer model users have claimed that if they wait a long period of time (40+ minutes) the problem sometimes resolves.rebooting the computer resolves the issue until it randomly occurs again changing the computer's mac address also resolves the issue until it randomly occurs again.

I have fiber optic Internet with static ip and keeps disconnecting at very random times. It started 3 weeks ago, before it worked perfect. Most of times dcing 3 times per hour. But sometimes working for hours without dcs. Usually disconnects only for half minutes then reconnect, it can be very annoying. The provider keep saying that need change router. I'm tried three different of routers already, but keeps disconnecting. I'm tried connect the net directly into my cpu, without router, but not worked, dc-ing too. I tried ping the default gateway when its disconnected, and its saying: request timed out.What else can i try? It should be, that the provider has too many clients, and their router collapsing?

I have a brand new Dell laptop running windows 7 connected to a sky router wirelessly. My internet connection randomly just drops. At 1st I could just click on the yellow triangle and troubleshoot and it would reset the network adapter. I cannot do that now - Im having to disable the adapter and the enable it and Im back on the internet.I have set it up so I am connecting via a manual IP address as I wondered if when the kids PS3 was connecting it was pinching my Ip address.

I've been having some problems with my new custom built computer connected wirelessly to my Router. My router is an SMCD3GN. So it is a Router/Modem in one. I am currently using the Linksys AE3000 Wireless-N USB Adapter. I have had a past Wireless USB Adapter, & an internal Wireless network card. The USB quit working & in order for me to get it to work is I have to reinstall the drivers everytime I turn my computer back on. The internal wireless network card would randomly lose internet every 30mins - an hour. Being a gamer, this is very frustrating. So, right now I am using the Linksys USB, and I was just playing a game & talking to some friends on skype & I would lose internet for 2 seconds then it would automatically reconnect. So I am beginning to think that it might be my Router but I tried my USB on my laptop for like 10 mins (I disabled the internal wireless network adapter) & I went into cmd.exe and pinged google for about 10 mins, & it said "Request Timed Out." several times.

I check all of the settings and changed the channel to see if it works. For some reason it disconnects my wireless internet at random times and i know before it never use to do that before with a older router. There is nothing blocking it, it worked before, and my computers can connect except two. The only thing i can guess is my wireless card.

We use our internet to watch Netflix. We have had no problems until recently, I called the satellite Internet company(which is a local co.) they told me my router was going out. I bought a new one, problem solved, my husband told me my neighbor just got Internet and has been playing Xbox everyday which coincidently is between the 5:30pm to 10ish pm we have been having issues with our router. What can we do to fix this? Do I have to buy a bigger router?

For about 7/24th of the day it'll be fine. But the rest of the day it will be riddled with burst packet loss. For example when I'm pinging.It'll go "Done
Done
Done
Done
Done
Request timed out
Timed out

Due to how it's only certain times it happens and other times it's perfect leads me to believe it's my ISP.

Where I try to download files and they do not download. They only download for a few seconds before not receiving any internet connection. Then after a few minutes they slowly download at only a few KB/s before completely not downloading. I also notice random slowdowns when browsing the internet or whatever I'm doing that uses the internet.

The router is being good so far. I have a Belkin Wireless G Plus MIMO router with windows XP operating system. This has been going on for a couple of weeks now and I really want it to stop because it is stopping me from doing things that require the internet.

We recently moved and upgraded our internet service from 1.5 Mbps to 4Mbps with CenturyLink. However, since our service was activated last Thursday, the internet connection intermittently drops and will not recover unless I reboot the modem. The period of up-time will last anywhere between fifteen seconds to several hours, usually falling along the five-to-ten minute range. No difference when using ethernet/wifi. The DSL light stays on, and the Internet light remains on as well.

I keep getting random moderate Nat sometimes, other times its opened. I have made a static Ip and port forwarded 4 ports that xbox uses. 88 udp..3074 both...53 both...80 tcp... Now when i test my connection on the xbox dashboard a message will come up saying make sure my UpNp is enabled, which it is and it tells me to make sure port 3074 is enabled which it is. I have restarted both my modem and router multiple times to try and fix this.
I have a linksys cisco e4200 and I recently updated its firmware which i thought would possibly fix the problem.I have talked to linksys but no luck.I have talked to my internet Cox Communication but they tell me its the router and i believe it is because when i directly connect my xbox to the modem i never get the moderate Nat. I have also talked to Norton about my virus protection because I thought maybe it was blocking some ports, but they disabled it and I still get the message.

We have a bunch of computers(70 aprox) connected to a domain. Since couple weeks ago very strange issues started occuring, internet and network access(path to network share is lost) would come up at random times and on different machines and would last for about 10-20 seconds it would re-connect again.All the computers are using private addresses.Most machines are windows 7, some are xp.Using Windows server 2003 as dc.Since the occurance is so random it's very hard to pin point the cause.

We have about 15-20 APs out in the field, and at random they seem to disassociate from the WLCs and re-associate within a few minutes. We have not looked into that entirely yet, but we are having an issue with a few. Sometimes, they will disassociate and after a few hours reassociate.

Since about 3 weeks ago my DSL has been getting totally random ping spikes, from under 40 to over 1500MS for minutes to hours on end. Nobody else is using my internet, I've verified this. There is nothing sucking up bandwidth on any connected device or computer, as far as I can tell through troubleshooting to the best of my ability. I tried switching to a Cisco X2000 modem/router combo and it did nothing, still totally random latency. Also, when I called AT&T about this, they didn't even know what ping was. They ran an upload/download speed test (which is still mostly consistent regardless of latency) and told me I was basically making the issue up.

I have a 2911 router hanging/freezing at random times, could work fine for a week then crash, or sometimes, could only go a few hours, completely random with timing. The onyl fix is to manually pull the power and reinsert.When this happens, all services/access stop working, including nothing on console access.This was on 15.2.1.T1 which im aware, has a few bugs, so i upgraded to 15.2.1.T2.The issue continued, so I swapped out the 2911 with a brand new one. The issue is still present.
One interesting thing, is when the router crashes/freezes, all lights appear to remain on working as usual, but when i unplug any of the ethernet links, the lights still continue to remain flashing and on for the ethernet LEDs, even once i have fully removed the cat6 cable.

The wireless drops specifically from my laptop constantly at random times. When the wireless drops in order for me to be able to reconnect i have to restart the router itself. There are also random times where the Wi-Fi stops broadcasting altogether. I have a computer connected via Ethernet and it does not lose connection during these times. All the computers are running Windows 7 and the Router is up to date on firmware.

Had an E4200 for a couple of months now and have not been able to resolve an issue with the router dropping an Apple iPad 2 at random times.The E4200 is replacing a Cisco Aironet 1200, which never dropped any clients, iPad 2 or others, and never displayed any of the issues below.
TECH DETAILS:The E4200 is being used purely as an access point. All extras are not in use and are disabled.
Firmware 1.0.03
Hardware version 1.
BASIC ISSUE:The E4200 drops an Apple iPad 2 off the 2.4 Ghz Mixed (B, G, N) network. The user must then select the network to rejoin. Rejoining occurs without incident. The same issue occurs when the network is restricted to B, G. The drops occur at what appears to be random intervals - sometimes 10 minutes apart, sometimes hours apart. We can have as many as 6 drops in an hour. A ping to the apple ipad shows the device stops responding to pings about 10 seconds before the user is prompted to rejoin a network. Meanwhile, a ping to the E4200 itself from a laptop connected via the E4200 on the same radio as the ipad continues to work without fail during this incident.
1. The iPad 2's cannot connect to the 5Ghz radio. I believe iPad 2's are supposed to support 5Ghz.
2. Both our Apple TVs do not connect to the 5Ghz radio: they fail with a "There was an error connecting to the network. Check your settings and try again. (-3914)" error. Apple TV supports 5Ghz.
3. The admin interface for the E4200 is very slow sometimes. Probably over 20 seconds to render some pages when it gets really bad. As a comparison, Internet-based pages on fast sites that delivered via the E4200 itself load in less than 2 seconds.
4. The HTTPS version of the admin interface can only be connected to via Safari browers. Both Internet Explorer 9 and Chrome 16 fail to connect with a "Connection reset" error. In Chome, it says "Error 101 (net::ERR_CONNECTION_RESET): The connection was reset." This is across multiple devices. There is no issue with straight HTTP.
All other devices - including Macs and PCs - connect fine with the E4200 on both 5Ghz and 2.4 Ghz radios, even if they cannot access its admin interface via HTTPS.I've presented quite a few issues above, but the main one is the drop outs for the iPad 2 devices. I'd present logs on drops, but the thing doesn't record any useful logs.
Basic wireless config:
5Ghz:
Network Mode: Wireless-N Only
Channel width: Auto (20 or 40 Mhz)
Channel: Auto (DFS)
SSID Broadcast: Enabled

We currently have around 150 2975 switches and have had problems with it them not handing out PoE power to the cisco phones and access points at random times. There is plenty of power left for the switch to use. We have at least 15 that will be running fine for about a week and then all of the devices that use PoE power will shut off and will not come back on until we reload the switch. If you console in there aren't any messages that pop up and if you look at the port it just shows on connected or will show IeeePD in the power inline. We have contacted Cisco TAC and they just RMA them.

I have setup the existing wifi router (couple of years ago) so do have the basic networking knowledge but am not up-to-speed with all the latest developments in the industry2. ISP have provided a '******' ADSL modem that i need to connect to get this whole netwrok working. its only supports ethernet connections - (i live in a third world country)3. I have installed a TP-link Wifi router (WR841Nd). The modem on stand-alone basis is fairly decent, covers decent range on ground floor (my house is fairly big and is double story building) but with few dead spots. It supports N series so speed is quite good as long as one is within range.
Problemi have been living with it for couple of years but since recently i have been experiencing a lot of drop-outs/random disconnections and slow speed. I have tested my wifi router at friend's place and it showed no signs of problems so it has to be my ADSL modem (phone line is fine, though i am not close to exchange but that is not an issues as my neighbours are using the same phone line/ISP and they dont have an issue)another problem i have is the coverage, my current wifi only covers the ground floor and i would like to extend this to upper portione am looking to change my ISP provided ADSL modem. The problem is i dont know if i buy an ADSL modem off amazon and whether it would work or not because the setup is not straight forward and the ISP staff is corrupt. They dont provide with quality hardware neither do they have technical competence so i literally have to beg them at time to at least come and see the problem.Question1: ISP provided ADSL modem replacementi know the settings for ISP modem so i can search how i can replicate the same with Billion but can this work?Question2: RAnge ExtenderI am thinking of buying couple of powerline wireless extenders from netgear.

I have a gaming machine i ran for some time on a wireless connection. This connection had decent speeds but was unreliable and at times very slow (3000 vent ping). So me and my father fished some cat5e cable through some wall from our router to my room. We used some old external jacks verizon gave us and some 6 foot patch cables to connect the computer and router to the jacks. My problem is that once it wall all connected the lan speed has been terribly slow (several times slower than the wireless). Previously I used an ASUS pce-n13 wireless adapter and now the lan is running of the nvidia nforce on my Asus P5n-d motherboard. I am clueless to the problem and I have called Verizon and gotten nowhere.

My problem occurs when i am trying to download something big, mainly the speed of the download raises at a peak and then it drops disconnecting me from the internet for a few seconds. This only happens when my laptop is on a wireless connection and this phenomenon repeats itself untill the download is complete. During the connection crash I am not able to access any site.
My laptop is an Asus G series with Win7 64bit SP1, and I use utorrent for P2P downloads.

I am having problems with my Netgear wireless moderm/router DGNG3700. since getting home tonight my internet connection has dropped out 3 times. The moderm /router is only 2weeks old and I have rang the Netgear technical support 4 times. The man I spoke to tonight said they are having trouble with this model and he told me to get the DGNG3700 version 2. I have changed the configerations and am very frustrated with the whole thing. Should I get a different Model altogether.

My internet (wired and wireless) usually works fine, but occasionally (read: every few days to weeks) the connection will suddenly black out for a period of time, anywhere from an hour to a day. I have tried resetting both my router and modem, and going through all the settings on my laptop, but I'm pretty sure it's not my computer, as no other devices can connect either. During the blackouts, when I look at the modem, the internet light will turn on for a second, then go off and then the red "alarm" light (aka "something is wrong" light) starts blinking like crazy, and this keeps repeating. This resolves itself after anywhere from a few hours to a whole day and everything is normal again. The light show, and the fact that I can't find any other problems, leads me to believe that it could be a problem with my provider (or the network itself) and not a hardware or software problem, but I can't be sure of this.Also, during the blackouts, I can connect to the network, but it shows that limited connectivity symbol (exclamation mark thing) and says no internet.

I am using a D-Link DIR-655 REV B (Firmware: 2.00NA) wireless router. The problem I keep having is that the internet will randomly disconnect and it happens to all my computers. I am not sure if it is the router or the modem that is causing this. The internet service provider that I am using is Time Warner Cable and the modem is an ARRIS TM502G.I have tried resetting the modem and the internet seems to come back. Same thing happens if I try to reset the router instead of the modem. I have also tried restoring the router to factory default settings and that didn't seem to work.

I am having a very frustrating issue with my wireless D-LINK 615 (firmware 5.0.1 NA). The internet connection drops constantly every 2-3 hours. Here are the settings on my router:
Cable modem
Modem Motorola Surfboard model SB6120
Code...
This seems to happen after I upgraded the firmware. Before that, did not get a complaint from my children or wife. Before I squeeze the last drop out of this lemon.
